Answer:
47.99g
Explanation:
The first step st have a balanced chemical reaction equation.
This is given as;
2Fe + 3Cl2 --> 2FeCl3
From the equation,
2 moles of Fe would react with 3 moles of Cl2.
I mole of Fe = 55.8 (3 s.f) (Molar mass of Fe)
2 mole = 2 * 55.8 = 111.6 g
1 mole of gaas occupies 22.4dm3
3 moles = 3 * 22.4 = 67.2 dm3
1dm3 = 1L
This means 116g would consume 67.2L
Xg would consume 27.8L
x * 67.2 = 27.8 * 116
x = 3224.8/67.2
x = 47.99g (2 d.p)
